The effect of Na+, Ca2+, Mg2+ and Cl- ions upon the solvent extraction of boron from aqueous solutions has been studied. The extraction of Na+, Ca2+, Mg2+ and Cl- ions singly and in various mixtures into 2-ethyl-1,3-hexa ...

Solvent-in-pulp extraction of boron from various slurries has been studied. Extraction of boron from synthetic slurries of quartz, bentonite and from natural plant-end-slurry from Kirka/Turkey with 2-ethyl-1,3-hexanediol ...

The aim of this study was to economically recover MnSO4 from low-grade manganese ores, abundantly available in the Southeastern Anatolia Region, and MnSO4 and silver from manganese ores containing silver. In the research ...

Solubility, adsorption onto mineral particles and entrainment of 2-chloro-4-(1,1,3,3-tetramethyl-butyl)-6 methylol-phenol (CTMP) in aqueous slurry phase are considered here. The results show that, the solubility at equilibrium ...

Changes in menstrual cycle length, menstrual duration, number of pads, dysmenorrhea and non-cyclic pelvic pain were studied in 43 women following tubal sterilization with three different techniques. One group consisted of ...

We have reevaluated analytically the vacuum polarization in Coulomb field using relativisitc Coulomb wave functions by a new regularization method. The result is finite giving the standard result in the lowest order of ...
